Application led .Tune 19, 1925.

This invention relates to a carboy holder. An object of the invention isto provide a simple and eiiicient holder for carboys in which thelikelihood of the carboy breaking is reduced to a minimum.

A further object concerns the provision of a simple and efficientliquidproof lining which, if the carboy happens to break, will preventthe fluid within the carboy from flowing out of the holder.

The invention is illustrated in the drawings, of which- Figure 1 is avertical section through the holder, and

Figure 2 lis a plan View.

In its general aspect the invention comprises a carboy holder,preferably in the form of a keg or barrel, suitable for con taining acarboy in which acid or corrosive liquid is disposed. This holder ispreferably lined on the inside with an acid-resistant compositionsuiliciently soft to withstand shocks without cracking. This lining maybe, and preferably is,l made of a mixture of pitch and tar, or paratn orresin and oil, with an inert material, such as asbestos, mineralorglass-wool, silica, talcum, fireclay, sulphur or graphite. Disposedbetween the carboy and this lining is a packing material,

which is preferably made of light voluminous material which ispreferably acidproof, such material being asbestos or mineralorglass-wool, infusorial earth or mica, preferably in the form of thematerial called zonolite, which is heat-treated mica, and alsocarbonized sawdust, or, in general, charcoal, coke or coal in the formof a coarse powder.

In accordance with 'the present invention the holder for the carboy islight in weight, occupies much less space than a square box, and is muchsafer, inasmuch as when a bottle or carbov breaks the acid will notimmediately run` out on the ground or the ioor or railway car orwherever the holder may be disposed, but will 4remain in the box for asufficient length of time to allow the acid to be emptied into anotherholder.

The preferred packing material is a light, .voluminous material, and theobject of using this packing inside ofthe lining is to reduce t'heweight, and insome cases we alternate rm layers of the lightwoluminousmate- The layi ers of mineral-wool act to keep the glass Serial No.38,363.

paint In the preferred form of the 'invention shown in the drawings, theholder comprises a keg or barrel provided with staves 11. Disposedwithin the keg is an acidproof lining which is sufficiently flexible toresisty cracking when the holder is jarred. Such a lining may be formedof various mixtures of pitch or asphalt and tar with an inert ma` terialsuch as asbestos, kieselguhr or a mixture of zonolite and slag-wool orsimilar material. Within the lining 12 is disposed a packing 13,whichimmediately surrounds the carboy itself. This packing 13 is an.vacid-proof, light material; it may be heattreated mica., kieselguhr or amixture of the heat-treated mica, with slagor mineralwool. In the lattercase, the mica and the slag-wool are preferably used in alternatelayers. The packing material is covered on top with a layer of tar paperor cardboard 14, and over this is disposed a layer 15 of the liningmaterial previously described and designated-12. This prevents moistureor Water from penetrating the packing. The top of the keg'is closed by acover 16." The neck of the carboy 17 projects slightly beyond the top ofthe keg in the usual manner.

In providing this construction of holder, therefore, we have enabled thecarboy to be disposed in a holder without the use of an excessivelyheavy material to cushion the carboy and prevent its being broken. Atthe same time we use these light-materials to cushion the carboy, wealso protect not only the outside ofthe holder from being affected bythe acid or corrosive mixture within the carboy in the event it isbroken, but we also provide means which will absorb a considerableportion if not all of the contents to prevent it being wasted.

1. A carboy holder comprising a container having a carboy disposedtherein, the

neck of the carboy extending. through the top of the container, a light,voluminous packing material surrounding the carboy,4v and an acidprooflining disposed between the packing material and the inner Walls of thecontainer and completely enclosing the packing material.

2. A carboy holder which comprises a container having a carboy disposedtherein, the neck of the carboy extendin through the top of thecontainer, pac ing material around the carlooy7 and a completelyenclosing acidproof lining around the packing.

3. A carboy holder which comprises a container, an acidproof liningcovering the inner Walls thereof, a light, voluminous packing Within thelining, a cover of suitable material disposed over the packing adjacentthe neck of the carboy and Within the lining, and a Wooden coverdisposed over the lining at the end of the container adjacent the neckof the carboy, the neck of the carboy extending through the top of thecontainer.
